Multi-component signalling in turtles and squamate reptiles
Brejcha, Jindřich ; Kleisner, Karel (advisor) ; Rehák, Ivan (referee) ; Carazo, Pau (referee)
Multicomponent signals are complex stimuli directed to receptors of only single modality. Colourful ornaments of animals are multicomponent signals. In this thesis I present results of studies on the origin of coloration in turtles and squamate reptiles together with notes on relativistic view of the functionality of animal coloration. The results show that turtle coloration, which have been studied only marginally until now, is shaped by sexual selection. It is shown that turtles share mechanisms of coloration by vertical organization of different pigment cell types together with squamate reptiles. Turtles also produce colour by organization of collagen fibres which share trait with birds and mammals. Mechanisms of body coloration differ dramatically between closely related turtle species studied even though the individual constituting components are shared among these species. On the example of polymorphic lizards, it is shown that qualitative categorical difference between groups of individuals of the same population are maintained based on quantitative changes in pigment contents regulated by ancient loci shared by different species. The turtles and reptiles are valuable source of our knowledge on the evolution of multicomponent visual signalling due to their intriguing composition of skin....

What Is Life and the Definition of Life in the Heart of Science of the 21st Century.
Pavlík, Richard ; Lhotský, Josef (advisor) ; Šolc, Roman (referee)
Phenomenon of life exceeds the science. Definition(s) of this concept should be a basis. This work discusses many sights around the definition of life and searching for the essence of life and it tries to embrace these factors in their entirety by quoting both traditional definitional approaches and the less traditional ones and possibly even futuristic ones. In a shortcut this text analyse instructions on how to define. Considering the extensiveness of the topic this bachelor's thesis touches thoughts of the scientific interdisciplinary framework. Keywords: definition of life, life and non-life transition, anti-definitionism, autopoiesis, cybernetical approach, biosemiosis

To thin from psychedelic experiences - a transdisciplinary interpretation
Pokorný, Vít ; Komárek, Stanislav (advisor) ; Horák, Miroslav (referee) ; Dadejík, Ondřej (referee)
Pokorný, V., To think from psychedelic experiences. Transdisciplinary interpretation. Diseration Thesis, Departement of General Anthropology, Faculty of Humanities, Charles University Prague, 2016 Abstract: The goal of this text is to think from and according to psychedelic experiences. To think from psychededic experiences means to introduce a transdisciplinary model of psychedelic domain. This model is based on autoethnographic, cognitive, phenomenological and psychopharmacological types of analysis. These analyses allow to demonstrate: 1) place of psychedelics in contemporary globalised czech society; 2) possible heuristic (theoretical and experiemental) value of psychedelic experience for understanding human situation. This text interprets psychedelic experience as a process of deteritorialization and reteritorialization that occurs on different, intertwinned levels of our experience, and, thus, it is a contribution to explication of a philosophical concept of intertwinning. Keywords: psychedelic experience, transdisciplinarity, autoethnography, cognitive anthropology, anthropology of experience, enactivism, phenomenology, embodiment, analogy, intertwinning
